What are Odds? 

They highlight the chance of an event occurring; lower odds = a higher probability higher odds = a lower probability. Odds can also be converted into a percentage; for example, odds of 1/1 (Evens) suggest a 50% chance of success. Online bookmakers will price up each event according to the chances of each outcome. In some sports, such as soccer, there are three options: Win, Lose or Draw, whereas in other sports, such as tennis, there are just two options: Player 1 Win or Player 2 Win. This will be reflected in the odds.
